A quadrant is any one of the four areas into which a space is divided by the $$x$$ and $$y$$ axes in the Cartesian coordinate system.

Problem solving with plotting coordinates

In this unit, pupils extend their knowledge of plotting coordinates from KS2 by now plotting non-integer values. Pupils learn that a set of points can satisfy a relationship and this understanding is built on in the sequences unit

In this unit, pupils learnt how to plot coordinates in all four quadrants via plotting positions and then shapes

In this unit pupils revisit and further develop their understanding of the coordinate plane, and learn how to plot non-integer coordinates. Pupils then plot from an equation both by hand and by using technology.

Plotting coordinates

The four areas into which the Cartesian coordinate system is divided by the $$x$$ and $$y$$ axes are called __________.

Match the coordinates to the quadrant in which you would find them.

Nothing. That's the coordinate $$(2,-2)$$

The signs are the wrong way round on both coordinates. It should read $$(-2,2)$$

What's wrong with the labelling of this coordinate?

This rectangle's sides are parallel to the $$x$$ and $$y$$ axes. What is the missing fourth coordinate? 

Nothing. Both the $$x$$ and $$y$$ axes are numbered correctly.

The $$y$$-axis does not change in equal steps. 

The $$x$$-axis does not change in equal steps. 

We call the vertical axis in the Cartesian coordinate system the __________.

5 in the $$x$$ direction, 2 in the $$y$$ direction.

5 in the positive $$x$$ direction, 2 in the positive $$y$$ direction.

From the origin, 5 in the positive $$x$$ and 2 in the positive $$y$$ direction.

Which language best describes this coordinate position?

We always use dots, not crosses to mark coordinates.

There is no comma between the $$x$$ and $$y$$ coordinates.

The $$x$$ and the $$y$$ coordinates are the wrong way round.

Match the coordinates for the vertices of this rectangle.

A coordinate is a single point, not a shaded region.

For the coordinate $$(2,4)$$ he should have gone four right and two up.

Alex says, "That's the coordinate $$(2,4)$$. I've gone right two squares and up four". What has Alex misunderstood?
